SCALE casina.

Application i'led August 25, 1923. Serial NO. 659,415.

This invention relates to improvements in casings for weighing scales and the like.

At the present time there is a considerable demand for weighing scales having a porcelain finish. Such scales are considered to be more sanitary than the krordinary enamelled. or painted scales, sincek porcelain culty is encountered in fastening adjacent parts together. These considerations have heretofore preventedthe use of sheet metal and necessitated the use of castingsy for various parts formerly made of sheet metal.

The use of such castings not only add to the expense but also necessitate complicated fastening devices which usually cause chipping of the porcelain surfaces.

The present invention isfdirected to the 'provision of a scale casing of such forni that porcelained surfaced sheet inetal stampings may be employed without the attendant ob jections heretofore experienced.

In the drawings,

Fig. 1 is a front `view of theupper part of a drum scale.y

Fig. k2 is a sectional 2 2 of Fig. 1. f

Figs.` 3 and 4 show details of construction.

In more detail, 10 has a casting forming the pedestaly of the scale. This casting has branched upper portions 11 suitably maohined at 12 to yreceive the drinn portion of the casing. 13 are frames, one at each end, which are secured by screws to the pedestal casting. These frames support the working parts of the scale, not shown.

The drum casingcomprises two sheet view taken on line metal plates l14, 15, having a substantially semi-circular contour (see Fig. 2) and provided with readingk openings, one being shown at 16 and the other below the projection 17. Theplates 14 and 15 have lower lip portions 18, which fit between rthe frame 13 and the pedestal as shown in Fig. 2. They are also provided with upper shouldered portions 19 which receive fastening screws 2O which hold the twov plates together andy into firm contact with the ring 13. The front reading opening` is covered with a bo):- like member 21 carrying the usual magnifying glasses 22. This part is secured to the plate 141 by screws Covering the upper junction of the two casing plates is a ychannel like sheet metal member 2&1-, which, at its ends, has tongue portions 25 (Figs. 3 and a). These. tongue portions are projected downwardly so as to liey in the saine plane with .the upper edges or corners 26-27 of plates 111 and 15.

After the cover plates 14 and 15 are as sembled and the channel 24 is placed in position, a pair of flanged end caps 28 are passed over the end plates 14 and 15, and the tongues 25. These caps are secured in position by suitable screws not shown and may be provided with glass covered openingsw29. The end caps also have depending portions 30 with suitable shoulders or flanges to engage over the ends ofbranches 11 of the pedestal casing. i

l In practice, it has been found that certain junction points in the casing are particulai-ly noticeable when the parts are porcelained.

To prevent the unsightly appearance of such linear junction points, I provide struckup beading formed directly in the sheet metal. This beading is shown at 31. The beading, which extends adjacent to and par allel with the linear junctions, to an ob* server appears to be a partof the design of the casing, but in reality it serves to obscure the wavy porcelain junction points.

lVhat I claim is:

l. In a casing for a weighing scale, in combination, with a supporting pedestal, of a drum casing therefor comprising a pair of substantially semi-ciircular sheet metal plates having shoulders at one end to restantiallj right angles to each other and haring a linear junction, and ineens in said sheet metal plate for obscuring` the junction ot' said part and plate7 said ineans including a beading struck up troni the inetal ot the plate and adjacent the said junction.

3. In a Weighing scale having a InultiplicitjT o't' cooperating parts including sheet inetal plate-like casing parts and other parts abutting thereaigainst and haringsuriace portions extending substantialljv perpendicularlv n'ith respect to the plane ot' surface o1' said plate-like parts, and beadingl in said casing; parts adjacent Vto and substantialljV parallel to the junction between the. parts Alor the purpose described.

l. A Weighing scale casing' including a pedestal` a pair or ring-like trames spaced apart and supported upon pedestal, a pair ot substantiallyv sein. irrular sheet metal casing nienibers haringi npturned shouldered portions one end thereoiu and lip portions at the other end thereo't'. said lip portions beingfitted between the Vtraine portions and the pedestal, adjustable tastentherethrough tor drawing said shouldered 35 portions together and securingsaid sheet nictal portions in position upon thev scale. a cap inenibcr disposed over and spaced ironi said shouldered portions and beine; supported directly upon said sheet ine/ia seinicircular portions of the casing, a pair oi end rings fitted over the ends of said sheet inetal portions. said rings also extending; over lip ineinhers extended troni the ends ot' said cap portion whereby said end rinus serve to hold said cap portion in position upon the sheet metal portions.

In testimonyv whereof l hereto ullix un' signature.
